Dirigible guide-light mounting mechanism for automobiles



w. v. VAN ETTEN 1812418 DIRIGIBLE GUIDE LIGHT MOUNTING MECHANISM FOR AUTOMOBILES Filed Nov. 29. 1930 June 30, 1931.

tencledthertathrough ancl said limb encl of the braeket is firmly clamped t0 the housing Wall by nuts placed thereon with the plate intervening. The plate serves to strengthen that part 0f the spring housing Wall to whicl1 the fixture is thus clamped by increasing the fric-' tional hold 0f the fixture 011 the housing.

There are two vertically disposed upper ancl lower bearing bosses 23, 24 integral with the braeket limlo 18 which have h0les therethrough in line to amount shaft 26 for oscillation therein and also for reciprocation in acljustment. Set ring 27 is mountecl 011 shaft 26 beneath bearing boss 24 ancl has set screw 28 therein to bear on the shaft to retain the ring in desirecl locations thereon ancl limit the upward movement of the shait't as desired. Set ring 29 with set screw 30 therein is mounteclon shaft 26 above upper bearing boss 23 with spiral spring 31 intervening. Set ring 29 is retained by set screw 30 at a location to cause suflicient reaction from the spring between the set ring and boss 23 to retain set ring 27 as a shoulder to the shaft against boss 24 and. support whatever load the shaft may be required to bear. The resilience of spring. 31 also serves t'o prevent rattling noises between the shaft anclits bearings ancl further serves t0 preserve eleotrical contact between then1 that they may provide an electrical conductorfor the lamp circuit as hereinafter mentioned.

A goose-neek bracket consistingof lag 32,

whieh has an opening through whieh shaft 26 is extendecl, neck 33 ancl ear 34, is securecl on the shaft, by set screw 36 engagecl in a threaded hole in the lug, near the upper end drive arm 37 firmlyto the axle shank with cylindrical part 48 of the nut serving as a bushing between the stud ancl the foot part. As above described, this eonstruction 0f nut ancl f0ot allows the nut to engage with the samethreacls 011 stud a15 as cliol the nut whi eh was removec l therefrom and, since the thickness of the foot a37 is somewhat greater than the length of the cylindrieal pa'rt of the nut,the nut can not bear on the axle shank to prevent the bearing of the foot thereon. This construetion allows the use of arm 15 andstucl a15 thereon and yet provid s secure fastening for my drive arm t0 the axle shank without requiring structural changes therein.

Arm 38 has lug 39 integral therewith ancl is provicleol with an opening through which the lower end 0f shaft 26 is extenclerl, and it is retainecl in clesired locations in both radial and reciprocal acljustments 011 the shaft by setscrew 41. Hol-e 40 in the outer end of arm 38 is parallel with the hole in lug 39 and is suited for the extension of stud a42 on ball 43 therethrough; also hole a4 0 in clrive arm 37 is parallel with the hole 40 ancl suited to receive one of the ball sturls. Shank 42 of ball 43 is larger than stucl a42 and provicles a shoulder to bear on t-he upper sicle 0f saicl arms when the stucls are extenclecl through holes 40 ancl d40 ancl elampecl by nuts engaged on the protruding threacled ends 015 the studs beneath said arms. One end of socket SleeV-e 44 is adapted t0 engageball 43 and the other end thereof is a threaclecl sleeve to engage a threadecl end f Connecting rocl45.

Set n uts 46 are placed 011 the threacled ends of the connecting rod before sleeV-es 44 are engaged therewith. The sleves are set on the Connecting rod t0 cause balls 43 to retain arms 37 ancl 38 in desirecl relation, which is usually paralled as shown in;Fig. 1.

Nuts 47, 48 are provided with pairs of slots 49 and when set in place on their bOlts a hole is drilled infea oh holt end registering With one of slots49 and a cotterypinis extended therethrough in the us1ial manner.

Lantern 50, housing an incandeScent electric lampnot shown, has ear 51 projecting from its bottom Wall with a hole therethrough. By mezns ofblt 52:this ear is elamped to ear 34 on the goose n'eekbjr'acket after the axis 01: the lantern is set in the de sired position. This axis looation is adjustable by use of the set'screw in the giooseneek bracket and also by clamping holt 52.

The electrical conduits for the lamp Socket, not shown, in lautem are shown at 53. One of these connects with one terminal of the cars battery, 1:10t shown, and the other is connected to the inost conv(anient clamping means on the frame work. As stated, spring 31 insures electrical contactsbetweizn shaft 26 and its bearings.

From the above description it should appear that bracket 18 is aclarted :Eor easy and secure attachment to the chassis, thatshaft 26 is readily 1cljustable both raclially and longitudinally, that the axis of lautem 50 is adjustalole in eleVation ancl also in both'horizontal and veitical planesand that but few parts and those of a simple ehairacter are required in my meohanism for mounting the lantern on the automoloile chassis and 0011- necting it to the steering gear to cause it to maintain close parallelism with the planes of the steering wheels. v

Having thus disclosed my invention, what I claim as new therein and desire t0 secure loy Letters Patent is, v

In a mounting mechanism for automoble dirigible guide lights a vertical-shaftbea1= ing bracket flange having an opening therein for extending therethrough the front spring hinge holt 0f said auto1nobile said opening larger than said spring hinge holt also having other openings therein f01 extending therethrough holte engaged with the housing Wall of the spring, am]. a cylindroangular nut 0n said spring hinge holt bearing on said bracket flange with the cylindrica1 portion thereof extended in the larger opening arouncl the spring hinge holt as a bushing thereto.
